Had a couple of hours before the football games started today.  Went out to 
the shop and continued cleaning some of the tools that were given to me two 
weeks ago.

Here are a 6" Brown and Sharpe tempered combination square (#4) and a Lufkin 
#511 depth gauge.  These were not rusty and required only non-abrasive 
cleaning.

There were a couple of traditional cape chisels and another that has a 
strange shape, or at least it looks a little strange to me (chisel at bottom 
of photo).  The tip is ground like a cape chisel, but the shape of the 
chisel is unusual.   It is marked "Hargrave #963 - 3/16"".  Is this a cape 
chisel, or some other type of metal chisel?

There were also a couple of drift pins and some sort of awl or punch.  It is 
not as narrow as an awl and the shank is made from a piece of 3/16" square 
stock which has been twisted into the shape shown in the photo.  Any reason 
for this twist, or did some tool maker have too much time on their hands?

I haven't seen it and held it in my hands, but..... If memory serves,  
when you cut oil grooves in a bearing, babbitt or brass, you need a  
cape chisel with a curved bottom surface to follow the curve of the  
bearing. Sort of like bent gouges for wood carving.

Solid bearings require oil grooves when the oil is not pressurized.  
They won't work long without them.

My best guess is that it was mostly decorative, but it would serve to  
improve the grip. I once made a simple device for twisting square  
stock, and for a time I put a twist on everything I got a hold of. I  
got over it in a short time though. I still have that thing somewhere.

I'm very fond of B&S (and B&S&D) if only because they're
not Starrett.

I find the view of a minority that Starrett are the ONLY
makers of quality metrology irritating.
